Toallwhomitmmy cof/teem: c,

Be it known that l, GABRIELE AoocnLLA, a subject of the KingO Great Britain, and residing at the cityof Montreal, in theProvince of Quebec, in the Dominion kof Canada, have invented a new` anduserul Surgical Instrument, ofwhich the Jfollowing isfthe specif ication. v

The invention relates to a surgical in-` strument as described in the present specification and illustrated in the accompanying drawings that form part of the same.. s

The invention Nconsists essentially ,of the novel Jfeatures of construction pointed out broadly and specifically in the claims for novelty following a description iin detail of the preferred form of the invention.

The objects of the invention are to furnish to the medical profession an instrument 'for the inspection of certain organs of the human body as well as for the treatment of the parts; to facilitate the practice of physis cians and insure accuracy in the treatment of hidden diseases; and generally to provide an etlicient means of inspecting and treating the urethra, cystolithic and other organs, such as uterus and pleura.

In the drawings, Figure 1 is a perspective view of the instrument.

Figure 2 is an inverted plan of the superior part.

Figure 3 is a plan View of the inferior part.

Figure 4 is an end view of the instrument.

Figure 5 is a cross sectional view on the line 5-5 in Figure'l.

Figure 6 is a cross sectional view on the line 6-6 in Figure 1.

Figure 7 is a longitudinal sectional View on the line 7-7 in Figure 4. A

Figure 8 is a perspective detail of a directing plate. Y

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the superior part 1 terminates in the solid reflector head 2 having the guiding rounded oset tip 3 to aid in the insertion in the passage and organ. The other end of the part 1 carries one half 4 of a disc end and this half has a serrated edge 8 at .the split and the Wire rod holes, 9 and 10.

The telescope 11 in a plurality of sections is mounted in the disc halt 4 and the inner section 12 is longitudinally fluted to fit into a grooved orifice in the disc half 13 at the `end of the inferior partvlt saidy disc halt 13 having the vserratededge 15 `matching the serrated edge `8. t i f Thedisc half 13 supports the glass tubes 16 and 17 and is formed with aboss 18 near the outer end, which projects outwardly to the extent of the solid end 2 beyond the groove 19 in said end into which theiint'erior part 14 slides, when the instrument is closed.-

The superior'part 1 and interior part 111 are formedto yslide ina tongue and groove n* `]o1n t 2O made in the interior so that the eX- t terior is perfectly-,smooth and withoutob- StuCtiQnn L i The directingplate 2 1' is a double curved and.` polished plate ,held lintermediately by the rod 22 and at the end by the rod 23 there'- by holding the plate in away to yadjust its angle to direct a catheter or other treating instrument `inserted through the tubes 16 and 17.

The lamp 24 in the form of tiny electric bulbs is mounted intermediate of the length of the superior part 1 and the lamp 25 is mounted in the head 2, which is a highly polished reflector, the inner surface' of the part 1 also being highly polished for the same purpose. s

1n the use of the invention the instrument is inserted in the passage tothe organ and Athen the inferior part is pulled back, which opens the superior part and discloses the organs within the scope yof the vision of the operator looking into the telescope from the disc end and at the same timev the op-y erator may insert a catheter or other instru p in its closed position by they thumb buttons 2G and 27 mounted on the disc-halt secured' to the superior part. The glass tubes are closed when not in use by the wire plugs 28 and 29 which completely till the areaof the tubes. Another opening 30 is shown in the disc half of the inferior tube which is closed by a suitable plug 31, and is intended for the passage of a surgical instrument.

What I claim is:

1. 1n a surgical instrument, a superior part having .a polished rinterior and a reiiectorhead, electric lamps in said part, an inferior part slidably connected with said superior part in a tongue and groove interior joint and adapted to disclose they lamps and reflector` surfaces to the extent desired and a spy glass end to said superior part.

2. ln a surgical instrument, a superior part having a solid head offset at the tip and an inner polished surface, an inferior part tongue and groove jointed in the interior to said superior part and iitting into a groove in said head and having a boss accounting for the beaded edge of said head, electric lamps in said head and superior part, a split disc mounted on. said parts and. a spy glass fixed to the disc halt secured to the superiorlpart.

3. ln a surgical instrument, a superior part having a polished inner surface and terminating in a polished reflector head, a disc halt mounted on the other end of said part, an electric lamp in said head, an electric lamp in said part away from said head, a spy glass having a plurality of sections and secured to said disc half, an inferior part slidably jointed to said superior part,

1,ass,oso

t. ln a surgical instrument a superior part having a disc haltl With a serrated edge at the split at one end and a reflector head at the other end, a spy glass in a plurality 01"' sections extending from said disc. half, a directing plate for auxiliary instruments and Wires for supporting and adjustingsaid plate projecting` through said disc half, electric lamps in said superior half, an inferior part slidably jointed to said superior part and'itting into said head, a disc halt itted to said inferior part and having a serrated edge matching the aforesaid serrated edge, glass tubes projecting through the dischalt of said inferior part and supported therefrom, and thumb buttons locking said disc halves and parts to their closed positions.
